Title: Method for manufacturing semiconductor device
Inventor: ONO TOSHIAKI
IPC: H01L21/20
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device capable of aligning an embedded pattern in subsequent lithography, even when a pattern shift is generated at formation of an embedded layer in an epitaxial growth step. SOLUTION: In this manufacturing step for a semiconductor device, a second conductivity-type impurity is subjected to local diffusion or ion implantation in a first conductivity-type silicon substrate 1 to form a pattern layer. A selective epitaxial growth layer is deposited on the patterned face thereof to form an embedded layer of an oxide film pattern 2. An epitaxial growth layer is selectively deposited on a part other than the coated part with an oxide film 11, in such a way that the oxide film 11 is left selectively on an alignment pattern formed on a face of a pattern face 6 of the silicon substrate 1. By using the alignment mark obtained when the oxide film 11 is removed, the position is aligned with the pattern 6 as a lower layer in the subsequent lithography process.

Title: Testing method for heat pipe
Inventor: MOCHIZUKI MASATAKA
IPC: G01M3/02
Filed: 1988-05-13
Abstract: PURPOSE:To easily decide the defect of the heat pipe in a short time by cooling the heat pipe temporarily and producing a vacuum inside, and then cooling part of it below the room temperature and measuring the temperature of a part which is not cooled. CONSTITUTION:The heat pipe 1 is put in a low-temperature thermostatic chamber and cooled below the boiling point of working liquid to condense the liquid, thereby producing the vacuum inside. One end part of the pipe 1 is inserted into a shower chamber 3 and the cooling liquid which is run through a cooler 6 is spouted to one end part of the pipe 1 to cool the pipe. Therefore, a room- temperature side part becomes a vaporization part and the cooled part becomes a condensation part; and the liquid flows to the condensation part, but if a pinhole is formed in the pipe 1 and air flows in, the air is confined to the condensation part side to decrease the area of the condensation of vaporized liquid. Therefore, the temperature of the room-temperature side part does not drop and is measured to decide whether or not the heat pipe is normal. Consequently, the defect of the pipe can easily be decided in a short time.

Abstract: PURPOSE:To prevent deterioration of display quality due to reflected light from side surfaces of spacers, by forming, at the same time as the electrodes are formed, shielding masks for shielding gas discharge light reflected from side surfaces of the spacers on the substrate on the display side at the positions to oppose the spacers. CONSTITUTION:On each surface of a pair of glass substrate 3, 4 is formed an electrode material film of chrome-copper-chrome three-layer structure by, for example, a sputtering method or evaporation method. The films are then subjected to a patterning process by photolithography and given predetermined patterns, and thus pluralities of X electrodes 5 and Y electrodes 6 are formed on respective surfaces. At the same time, shielding masks 10 are also formed by patterning with the same electrode material on the surface of the glass substrate 3 on the display side at the positions opposing the spacers, wherein the shielding mask 10 has a larger area than the area to be occupied by the spacer 9. Thereafter, dielectric layers 7 and sealing material layers 8 are formed in succession and the spacers 9 are disposed. And then the substrates 1, 2 are sealed up in a predetermined sealing process.

Abstract: PURPOSE:To adjust an angle in all directions as well as to prevent any lost motion from occurring by installing a holding part, sliding in a box body and formed into a circular form of the tip part, of electronic equipment capable of storing an image display part after sliding in this box body and another holding part turning round in the vertical direction along the former. CONSTITUTION:A holding part 9 slides a display 1 to the outside of a box body 10 by means of motor drive via another holding part 4 in a state that its tip part is pressed by respective holding parts 4 and 12. In succession, when a turning shaft 2 is rotated by hand and the display 1 is turned in the vertical direction, it is adjustable as far as an optional angle in the vertical direction. In addition, In a state that the display 1 is slit to the outside of the box body 10, if a turning shaft 8 is manually rotated, this shaft 8 turns round in the right direction along the tip part of the holding part 9 with it as the fulcrum. In consequence, since it is turned round in the longitudinal direction via the turning shaft 2 locked to the outside of the holding part 4, it is adjustable as far as an optional angle in the longitudinal direction. Therefore, as this holding part is a separate one, any lost motion is not produced there at all.

Title: Semiconductor radiation detector
Inventor: FUJITA YURIKO
IPC: H01L31/09
Filed: 1987-05-14
Abstract: PURPOSE:To detect an ionization current with high efficiency, by changing the intensity of the n-type region formed to a low specific resistance p-type CdTe single crystal in accordance with the intensity of the energy of a radiation source. CONSTITUTION:An n-layer 2 is formed, for example, by applying Al to one surface of a low specific resistance p-type CdTe single crystal wafer 1 by vacuum vapor deposition and subsequently heating said wafer 1 for a predetermined time to thermally diffuse Al while an ohmic electrode 3 is formed by applying an aqueous gold chloride solution to the other surface of the wafer 1. For example, gamma-rays incident to the n-layer 2 in this constitution lose energy in the wafer 1 to form an electron-hole pair. This electron-hole pair becomes an output current since an electron is taken out on the side of an Al electrode and a hole is taken out on the side of the Au electrode 3 by the diffusion potential in the depleted layer formed by the pn junction being the boundary of a p-layer and the n-layer. This current is amplified by an I/V converting amplifier 5 through a lead wire 6 to be converted to voltage. The depth of the n-layer is increased with respect to high energy radiation and reduced with respect to low energy radiation. By this method, an ionization current can be taken out with high efficiency.

Abstract: PURPOSE:To simply change the temperature characteristic of an Rb atomic oscillator by winding a coil for a static magnetic field generating in the cavity circumference of an optical resonance part, further winding a cavity heater in the upper part and equipping a cavity temperature adjusting device consisting of a transistor and a resistance. CONSTITUTION:A current is supplied from a power source 7 to a C-field 6 as a current for a frequency adjusting. When a current is supplied through resistances 9 and 10 to a frequency compensating coil 8, the frequency of an Rb atom oscillator is changed by the level of a heater voltage VH. The compensating resistances 9 and 10 are selected so that a changing quantity can correspond with the frequency temperature fluctuation quantity. Thus, it is not necessary to compress so severely the change of the frequency temperature characteristic of a gas cell or the temperature characteristic of the temperature controller of a lamp part or a cell part and by changing the current of the compensating coil 8 with the change of a resisting value, the temperature characteristic of the Rb atom oscillator can be easily improved.
